An　industrial　prototype　of　single-stage　end-pumped　fiber　laser　at　1080　nm　has　been　demonstrated　and　developed.　The　corresponding　optical-to-optical　conversion　efficiency　is　73.3%　with　a　pump　power　of　2066　W　and　output　laser　power　of　1515　W.　The　total　laser　power　fluctuation　is　less　than　0.9%　within　one　hour.　The　stimulated　Raman　scattering　(SRS)　is　well　suppressed.　The　cladding　light　stripper　(CLS)　is　optimized　and　integrated　with　three　regions　of　particle　mixture　and　gel.
